IINSULATOR FOR HlGH-TENSIION LINES" Specification of Letters Patent.

Patented May 15, 1906.

Original application filed October 31,1903, Serial No. 179,376. Dividedand this application filed October 1,1904. $crial No. 226,795.

To all whom it may concern:

Be it known that I, EMILE GIRAUD, engi-- neer, a citizen of the Republicof France, residing at Paris, 18 Rue Royale, in the Repub lie of France,have invented a new and useful Improvement in Insulators forHigh-Tension Lines, of which the following is a specification.

This invention is a divisional application of Serial No. 179,376, datedOctober 31, 1903, and relates to an insulating apparatus intended forhigh-tension lines and so arranged or fitted up as to automatically putthe line-wire in communication with a discharge or return conductor whenthe said wire is broken at any point in order that the falling portionsof the falling wire shall not be dangerous. In the said apparatus asocket is fixed. on a porcelain head or bell, andthrough which is freeto slide a tube fixed onto the linewire. On the ends of the socket arepivoted contact-arms, the ends of which are adapted to meet adischarge-conductor. On the other hand, the ends of the tube on the wirecarry members which engage with the said arms and cause the same toswing when the wire is displaced to one side or the other-that is, whenthe wire is broken. In this swinging motion one of the arms meets withthe discharge conductor, so that the portion of the line-wire leading tothe insulating apparatus is discharged of the dangerous current throughthe said. arm. and the said conductor.

In the accompanying drawings, Figure 1 is an elevation of an apparatusshown in the position of rest, and Fig. 2 is a corresponding plan Viewshowing in dotted lines an operative position of the same.

The head 15 of the insulator is stationary and carries a socket 22,which is stationary also and in which a split tube 23 is freelyslidable. The line-wire S is fixed in the tube 23 and clamped therein byclips 24, located on the said tube and which are assed through by bolts25. On the ends of the socket 22 are.;tixed clips 26, provided withpivots 27, around which are free to rock rods 28, which extend outwardon each side and pass freely through eyes 29, formed on the clips 24.Each rod 28 is provided with an arched part 30, in such a manner thatwhen the tube 23 moves longitudinally, the eye 29, sliding on the saidarched part, causes the rod 28 to move round the fixed pivot 27, asshown in dotted lines in Fig. 2. The rod 28 may be bent at right anglesat its free end so as to meet in thus turning round a conducting-wire(not shown) arranged parallel to the line-wire 8 or another conductorsuitably arranged. The said discharge-conductor may be put in anyposition, for the socket 22 with the arms 28 can at will be set in sucha direction that the said arms will swing in a plane which is more orless inclined.

I claim 1. An insulating apparatus for high-tension lines, comprising afixed insulating-head, a socket fixed on the said head, arms pivoted tothe socket, a tube adapted to be fixed on the line-wire, members on thesaid tube to engage with the said arms, and a discharge-com ductor soarranged as to be met by the said arms.

2. An insulating apparatus for high-tension lines, comprising a fixedinsulating-head, a socket fixed on the head, arms pivoted to the socketand having a curved part and a bent end, a tube slidable in the socket,eyed members on the said tube and through which the arms pass, and adischarge-conductor so arranged as to be met by the bent end of the saidarms.

3. An insulating apparatus for high-tension lines, comprising a fixedinsulating-head having a socket, a tube slidably mounted in the socket,means for securing the tube to the line-wire, arms pivoted to the socketand nor mally lying substantially parallel therewith, and means wherebythe movement of the tube through the socket may swing the armtransversely thereof.

4. An insulating apparatus for high-tension lines, comprising aninsulating-head having a socket for receiving the line-wire, armspivoted to the insulator and normally lying substantially parallel withthe line-wire, and connections between the line-wire and the armswhereby the movement of the wire through the socket may swing the armstransversely thereof.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

EMILE G'IRAUD.
